by virtual of their position at the interface between truly terrestrial ecosystems and aquatic systems, belong to the most dynamic and fascinating ecosystems on Earth They are among the most productive ecosystems on our home planet, providing numerous ecological, economic, cultural, and aesthetic benefits and services Meanwhile, they are also the foci of human settlement, industry, and tourism Because of large population and intense development, global coastal ecosystems are under strain as never before and there is a strong need for environmental monitoring and assessment in order to manage and protect these sensitive areas more effectively This in turn requires reliable information bases and capable analytical techniques Conventional field-based survey and mapping methods are still vital but often logistically constrained Because of cost-effectiveness and technological soundness, remote sensing and geospatial technologies have increasingly been used to develop useful sources of information that support decision making as related to many coastal applications But coastal areas comprise complex, dynamic landscapes, thus challenging the applicability and robustness of these methods and technologies Encouragingly, recent innovations in data, technologies, and theories in the wider arena of remote sensing and geospatial technologies have provided scientists with invaluable opportunities to advance the studies on the coastal environment Within the above context, a book on coastal ecosystems is timely This book focuses on the development of remote sensing and related geospatial technologies for monitoring, synthesis and modeling in the coastal environment The book is divided into three major parts The first part examines several conceptual and technical issues of applying remote sensing and geospatial technologies in the coastal environment The second part showcases some latest development in the use of remote sensing and geospatial technologies for coastal ecosystem assessment and management with emphasis on coastal waters, submerged aquatic vegetation, benthic habitats, shorelines, coastal wetlands and watersheds The last part details a watershed-wide synthetic approach that links upstream stressors with downstream responses for integrated coastal ecosystem assessment and management v vi Preface This book is the result of an extensive research by interdisciplinary experts, and will appeal to students and professionals dealing with not only remote sensing, geospatial technologies and coastal science but also oceanography, ecology, environmental science, natural resources management, geography and hydrology in the academic, governmental and business sectors The Editor is grateful to all the contributing authors and

northward flow from the outlet for turbidity was confirmed by stations to the north yielding significantly higher values than those to the south at 50 m and 200 m offshore The fact that this trend was not observed at 100m offshore may be explained by the irregular bathymetry of the northern transect The three stations O1, O2, and O3 located 50 m, 100 m, and 200 m along this transect have depths of 4.4, 6.1, and 4.2 m, respectively According to Fick’s Law, the concentration at any location will be inversely proportional to the location’s depth during dispersion of a given flux Thus, the greater depth of station O2 could explain its turbidity levels being lower than that of the further station, O3 The use of an appropriate statistical model, in this case the matrix normal model and the corresponding modified ANOVA F-tests (Dutilleul and Pinel-Alloul 1996), proved to be essential to a sound comprehension of our results Station effects of TSS in the reef area were finally declared non-significant at the 5% level, although had the ANOVA F-test not been modified the effects would have been found to be significant Thus, the use of the matrix normal model avoided the generation of artifact effects, which were in fact due to the spatial autocorrelation and heteroscedasticity of the data The lack of spatial effects in the distribution of plume waters over the reef indicated that if an event’s plume reaches the reef, it will affect the entire reef similarly While this suggests that different zones of the reef will be affected equally by poor surface water quality, the implications may be greater for the reef crest This zone takes the brunt of the wave action and has far poorer coral species diversity than that of the spur and groove zone (Lewis and Oxenford 1996) Wave action may be considered a chronic stress upon coastal ecosystems (Grigg 1998; Tewfik et al 2007) Perhaps the added stresses of eutrophication and sedimentation restricting coral growth in the crest zone are thus inhibiting the coral’s resistance to the zone’s naturally turbulent environment In addition to the potential effects caused by the estimated nutrient loads, eventwater plumes with detrimental levels of turbidity and TSS could be termed a chronic stress to the Bellairs Reef as flow events occur every year and all of the events sampled produced detrimental water quality levels above the reef making this a predictable seasonal disturbance Of the events for which second sets of seawater samples were taken, the two largest events both caused initially high TSS levels that did not recede within 67 hours from the onset of flow It thus appears that large events can cause poor water quality to linger above the reef but further sampling is needed to confirm this and establish the full duration of influence Few flow events occurred this year until late November when more frequent flows from the outlet restricted reformation of the beach separating the lagoon from the sea Residents of Holetown state that this flow regime usually dominates much more of the rainy season, and rainfall in the watershed was below average for the year (unpublished data, Caribbean Institute for Meteorology and Hydrology), suggesting that more than the observed flow events would normally occur In fact, adjacent watersheds to the north and south atypically did not generate runoff at all in 2006, 22 Runoff Water Quality, Landuse and Environmental Impacts 547 minimizing stress incurred by the Bellairs Reef due to additional sources of runoff During the final stages of the study period, when the lagoon flowed continuously and wave heights were highest, sedimentation rates on the reef were far above the recommended guidelines Such heavy surf continues for months into the dry season potentially sustaining high sediment resuspension rates While the complexities of coastal sediment transport exceed the scope of this study, the documented terrestrial sediment loads represent a significant contribution to the nearshore zone and thus the excessive levels of sedimentation observed on the reef Excessive sedimentation commonly decreases coral diversity as few species are resilient to such conditions (Cortes and Risk 1985) Large branching corals can typically survive the stress of sedimentation as their morphology limits the accumulation of sediment on their surfaces (Rogers 1990) However, the proliferation of such corals may impede the resilience of a reef’s coral community as their tolerance to sedimentation is counterbalanced by their susceptibility to large waves (Blanchon and Jones 1997) For example, the southern part of South Bellairs was once densely covered by the branching coral Porites porites (James et al 1977) until the passing of Hurricane Allen in 1981 destroyed 96% of this species (Mah and Stearn 1986) 22.4.3 Recommendations The first flush phenomenon observed in TSS at the watershed’s outlet shows that if any efforts were made to reduce sediment fluxes to the sea, this could efficiently be done by retarding as much of the initial discharge as possible to allow for settling, and protecting the accumulated sediment from erosive action during future events In this regard, it has been suggested to divert the tributary upstream of site NB into the nearby quarry (Cumming Cockburn Ltd 1996) The present study supports that this venture would not only be a viable solution for reducing runoff peak flows but turbidity, TSS, and SRP loads as well Capturing only half of the runoff would capture 80% of the TSS, and the tributary to the north has been shown to be contributing the highest concentrations per unit area of land Given the low proportions of agricultural and urban landuses, it appears that excessive application of fertilizers is occurring A recent survey of farmers in a nearby watershed revealed that none were aware of the fertilizer quantities being applied (Denis and Hughes 2003) Though not an immediate solution, it is likely that agricultural practices will eventually require improvement and control as ongoing farming development and population growth will only expand agricultural landuse Increases in the island’s local and tourist populations will also enhance the potential for wastewater contamination of runoff Remediation of this problem has been addressed and awaits the progress of the West Coast Sewerage Project (Stanley International Group Inc 1998) An additional solution would be to phase out the use, or importation, of soaps and detergents containing phosphates This last solution would be beneficial to conservation of the nearshore marine environment considering the large SRP load shown in this study and that phosphorus has been 548 M Tosic et al suggested to be the nutrient limiting algal growth (Sander and Moore 1979; Wellington 1999) However, it appears that water from the coastal lagoon flushed by runoff events presents a greater dissolved phosphorus load than that delivered by the runoff itself This lagoon has a volume equal to 10% of an average flow event’s total discharge, meaning that regardless of all the upstream nutrient sources, the most efficient means for reducing phosphorus loading would be to control this lagoon’s point-sources These sources are known to have been discharging large quantities of phosphorus for a long time (Brewster 1990; Braithwaite 2004) 22.5 Conclusions Water quality in the watershed is much poorer than it ought to be with such a high proportion of natural land While high-flow events have a much higher potential for transporting solids, similar nutrient concentrations were observed in high- and low-flow events alike The high levels of TSS, turbidity, and SRP in the most developed subbasin support the hypothesis of sources being agricultural, urban, and industrial areas The first-flush phenomenon observed for TSS and turbidity shows that most of the runoff’s sediment content is transported rapidly Sources are most likely those where solids are abundant and unstable such as the various construction sites and the fields of by-product storage at the sugar factory This hypothesis is supported firstly by elevated TSS and turbidity levels drained from the areas with large industries, and secondly by lower levels coming from a subbasin containing no industries, a small urban area, and greater agricultural landcover relative to the rest of the watershed The reported nutrient concentrations are quite high considering what little agricultural land remains Expected reductions in nutrient contamination due to the demise of agriculture in the watershed’s recent history may have been offset by increased fertilizer application in the remaining areas and urban growth Identification of agricultural areas as sources of nutrients is supported by high nutrient concentrations found draining from a subbasin with relatively larger agricultural and smaller urban landcover Pastures, on the other hand, yielded much smaller concentrations of nutrients Runoff into the nearshore zone of Holetown causes plumes in excess of the MPCA guidelines for turbidity (1.5 NTU) and TSS (5 mg/l), and delivers large loads of sediments and nutrients contributing to the chronic effects of eutrophication and sedimentation Including water from the Holetown lagoon, surface water flushed by runoff events appears to be the chief source of SRP to the nearshore area, doubtlessly enhancing coastal eutrophication as phosphorus has been cited in the literature as the limiting nutrient for algae growth (Sander and Moore 1979; Wellington 1999) Plumes around the outlet revealed a trend of northward flow towards the Bellairs Reef This study’s data show that the magnitude of post-discharge changes in the seawater depends on a flow event’s TSS load and total discharge, which were proportional for the three events monitored in the outlet area In the reef area, factors 22 Runoff Water Quality, Landuse and Environmental Impacts 549 controlling seawater quality changes included TSS load and total discharge, as well as the strength and direction of prevailing winds Turbidity levels were above the MPCA guidelines for less than 2–3 days following events but TSS levels showed the potential to remain high for at least three days following the sampled events Sedimentation represents a definite chronic disturbance as accumulation rates on the reef were far above the recommended guidelines for 35 of the 118 days monitored, and were near the threshold on North Bellairs for an additional 26 days The fringing reefs of Barbados are still recovering from the acute disturbances which occurred over 20 years ago as their recovery is impeded by the chronic disturbances of eutrophication and sedimentation resulting from land-based sources (Bell and Tomascik 1993) Remediation of the degrading seawater is critical to the health of the reefs (Bellairs Research Institute 1997) If measures are taken to improve water quality, there is potential for the reef’s subsequent improvement A recent study on the island’s south coast revealed ecosystem recovery following local improvements in seawater
