Comparison of Flood Frequency at Different Climatic Scenarios in Forested Coastal Watersheds

چکیده
Climate change-induced extreme precipitation causes coastal flooding. A streamflow simulation in watersheds, Wolf River Watershed (WRW) and Jourdan (JRW), was conducted using the Soil Water Assessment Tool (SWAT) to compare variation flow at different climates analyze flood frequency. Baseline models were auto-calibrated with SWAT calibration uncertainty programs (SWAT-CUP). Kling–Gupta efficiency (KGE), defined as objective function SWAT-CUP, ranged from 0.8 0.7 WRW 0.55 0.68 JRW during calibration–validation process. Results indicated reliability of model performances. Monthly averaged baseline 1% greater than historical 8.9% lower future climate WRW. In JRW, monthly 11% 5.7% climate. Flood frequency analysis showed highest exceedance probability annual maximum series (AMS) WRW, whereas AMS projected estimated JRW. This study aids preparing for management.

Hydrology and Water Quality of Two First Order Forested Watersheds in Coastal South Carolina
Abstract Two first-order forested watersheds (WS 80 and WS 77) on poorly drained pine-hardwood stands in the South Carolina Coastal Plain have been monitored since mid-1960s to characterize the hydrology, water quality and vegetation dynamics. This study examines the flow and nutrient dynamics of these two watersheds using 13 years (1 969-76 and 1977-81) of data prior to Hurricane Hugo (1 989) ...
متن کاملFlow Dynamics of Three Experimental Forested Watersheds in Coastal South Carolina (usa)
Three first-, secondand third-order experimental forested watersheds located within the Francis Marion National Forest in the lower coastal plain of South Carolina were monitored for rainfall and stream outflows. The largest watershed (WS 78) with some open lands, roads and wetlands gave higher annual water yields compared to the two other smaller ones (WS 79, WS 80) with mostly forest vegetati...

the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...
Comparison of Artificial Neural Network, Decision Tree and Bayesian Network Models in Regional Flood Frequency Analysis using L-moments and Maximum Likelihood Methods in Karkheh and Karun Watersheds
Proper flood discharge forecasting is significant for the design of hydraulic structures, reducing the risk of failure, and minimizing downstream environmental damage. The objective of this study was to investigate the application of machine learning methods in Regional Flood Frequency Analysis (RFFA). To achieve this goal, 18 physiographic, climatic, lithological, and land use parameters were ...
متن کاملComparison of sample preparation methods for stable isotope analysis of dissolved sulphate in forested watersheds.
Pretreatment methods for measuring stable sulphur (δ(34)S) and oxygen (δ(18)O) isotope ratios of dissolved sulphate from watersheds have evolved throughout the last few decades. The current study evaluated if there are differences in the measured stable S and O isotope values of dissolved sulphate from forested watersheds when pretreated using three different methods: Method 1 (M1): adsorb sulp...
