One of the major problems confronted by the hydrologists for many years is the prediction of runoff from a given basin for a known rainfall. In this situation, development of a rainfall runoff model is important in Veeranam tank catchment located at latitude 11° 15’00” and longitude 79° 30’00’ E in Cuddalore District of Tamilnadu, India. By considering the above said aspect the rainfall-runoff ...

[1] The augmented Noah land surface model described in the first part of the two‐part series was evaluated here over global river basins. Across various climate zones, global‐scale tests can reveal a model’s weaknesses and strengths that a local‐scale testing cannot. In addition, global‐scale tests are more challenging than local‐ and catchment‐scale tests. Given constant model parameters (e. g...

Seepage zones have been shown to be of critical importance in controlling contaminant export from agricultural watersheds. To date, no multipurpose agricultural water quality model has seepage zones incorporated into its process-level representations. We chose to test two widely used models of agricultural water quality, the Groundwater Loading Effects of Agricultural Management Systems (GLEAMS...

The correlation of runoff phosphorus (P) with water-extractable phosphorus (WEP) in land-applied manures and biosolids has spurred wide use of WEP as a water quality indicator. Land managers, planners, and researchers need a common WEP protocol to consistently use WEP in nutrient management. Our objectives were to (i) identify a common WEP protocol with sufficient accuracy and precision to be a...

Distinct seasonal characteristics of monsoon climate significantly affect river streamflow in South Korea. The roles of direct runoff and baseflow on streamflow have become more important to ecosystems and human communities in various watersheds of South Korea. Understanding river characteristics, including direct runoff and baseflow, is the first step of river management and can make a signifi...

Hydrological drought is assessed through river flow, which depends on runoff and water withdrawal. This study proposed a framework to project future hydrological droughts considering agricultural withdrawal (AWW) for shared socioeconomic pathway (SSP) scenarios. The relationship between AWW potential evapotranspiration (PET) was determined using deep belief network (DBN) model then applied esti...
