RAINFALL-RUNOFF SIMULATION OF A SUB-CATCHMENT USING HEC-HMS

Platform, a Journal of Engineering, 2022
Hydrological data in the form of stream flow is very scarce in most developing countries. This affects the planning and management of urban watersheds. Therefore, it is necessary to estimate peak discharge from rainfall using hydrologic models based on ...

GIS-based modeling of runoff source areas and pathways [PDF]

Geographica Helvetica
The application of runoff models that rely on calibration to future land use and climate conditions is restricted to situations where the reaction of Hydrologic Response Units to environmental change is known.

Rainfall prediction in the northeast region of Thailand using Cooperative Neuro-Fuzzy Technique

, 2012
Accurate rainfall forecasting is a crucial task for reservoir operation and flood prevention because it can provide an extension of lead-time for flow forecasting. This study proposes two rainfall time series prediction models, the Single Fuzzy Inference

Proglacial lake records of Holocene glacier behaviour and catchment processes in Slettedalen, Northeast Greenland

Journal of Quaternary Science, EarlyView.
ABSTRACT Constraining Arctic catchment response to Holocene climate change is vital for understanding future environments. We present detailed sedimentological, geochemical and grain size end‐member analysis of two Holocene (~7.0 ka to present) lake sequences, S1 and S2, close to Zackenberg, Northeast Greenland.

Effect of spatial scale on runoff coefficient: Evidence from the Ethiopian highlands

International Soil and Water Conservation Research, 2018
The runoff coefficient (RC) is the ratio between the runoff and rainfall amounts and is scale dependent, which is due in part to the heterogeneity of watershed characteristics.

Salmonella enterica serovars co‐exist sporadically and at low abundance in US mid‐Atlantic irrigation ponds

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Spring or rain‐fed ponds are frequent features on US mid‐Atlantic farms. The need to conduct preharvest agricultural water assessments to identify microbial hazards, as required by the US Produce Safety Rule, highlights knowledge gaps pertaining to pond water adequacy for vegetable production.

Assessing the Role of Spatial Rainfall Variability on Watershed Response based on Weather Radar Data (A Case Study of the Gard Region, France)

International Journal of Technology, 2018
The primary input for hydrological the hydrological model is rainfall. The accurate illustration of rainfall in time and space is important for rainfall-runoff modeling since it impact the hydrological responses.

Conceptual Rainfall–Runoff Model Performance with Different Spatial Rainfall Inputs

, 2011
Different methods have been used to obtain the daily rainfall time series required to drive conceptual rainfall–runoff models, depending on data availability, time constraints, and modeling objectives.

Precision Restoration to Minimize Soil Loss in a Watershed in the Atlantic Forest Domain

Land Degradation &Development, EarlyView.
ABSTRACT The Turvo River Watershed, located in the Zona da Mata region of Minas Gerais and part of the Doce River Basin, faces serious problems of erosion and soil degradation, which compromise and reduce the quality of local water resources. Given this scenario, it is essential to implement environmental recovery strategies that prioritize the ...
