“…This water balance was supported by a rain-runoff relation, where runoff is a fraction of annual precipitation volume, and it is also calculated based on the basin delineation. International literature reports diverse methods to estimate this relationship [7,19]. Therefore, the river basin boundaries are critical to identify the terms of the continuity equation and to define their magnitude.…”

River basin delineation can be inappropriate to determine surface water availability in a country, even if it is established by its water authority. This is because the effect of agricultural and urban infrastructure in runoff direction is ignored, and the anthropogenic changes in hydrography and topography features distort the runoff. This situation is really important because water rights are granted based on volumes that are not physically accessible. The existence of this problem is demonstrated through a case of study: the Culiacan River Basin in Mexico. To overcome such a situation, this study poses criteria to revise official river basin configurations and to delineate new river basins based on digital elevation models, vector files of agricultural infrastructure, and extensive field verification. Significant differences were noticed in surface water availability calculated under distinct river basin delineations.

“…Land use and management types have been used in the preparation of hydrological soil-cover complex, which has been utilized in estimating direct runoff. Antecedent Moisture Condition (AMC) is an indicator of watershed wetness and availability of soil moisture storage prior to a storm (Rawat & Singh, 2017). SCS has developed a guide for adjusting CN according to AMC based on total rainfall in the 5 day period preceding a storm.…”

“…The capabilities of these technologies have been successfully utilized by many researchers in rainfallrunoff modeling . Earth-observing satellite provides more reliable input parameters for hydrological modeling (Rawat & Singh, 2017;Maliqi & Singh, 2019). However, GIS processing has become a critical step in hydrologic modeling (Thakur et al, 2017), since it contributes to generate model parameter distribution in spatial manner.…”

Generally, runoff records are the most important input data in water resource management; however, their availability is very limited especially in developing country as compared to rainfall records, especially under medium and small-scale catchments. In our study, we estimated runoff from ungauged agricultural watershed with the curve number method and empirical mathematical models were compared with SCS-CN. Empirical mathematical models (Inglis and De Souza Formula (IDS), Turc relationship (TR), Indian Irrigation Department (DII) model, Coutagine relationship (CR), Khosla method (KH), Justin Equation (JE), Lacey relationship (LR), and Indian Council of Agricultural Research (ICAR)) model were used to estimate annual runoff (in cm). It was found that IDS model has capability to simulate annual runoff as very close to Soil Conservation Service Curve Number (SCS-CN) model and has lowest Root Mean Square Error (RMSE) value as 7.75, and ranking of this model (based on K factor (value of 0.001) analysis) was topmost (or 1 st) in comparison to other eight models. This study suggests that empirical mathematical model has potential for annual runoff estimation from ungauged watershed.

Morphometric analysis gives a quantitative description of drainage basin. The main aim of the present study is to identify the morphometric parameters of a watershed of Mula River basin, Pune district of state Maharashtra, India, and to prioritize the sub-basin. The work outlines the significance of digital elevation model for assessment of drainage pattern and extraction of relative parameters. Basin has been divided into 5 sub-watershed namely SW1 to SW5. The stream order of watershed ranges from first to sixth order and have dendritic drainage pattern means homogeneity in texture and lack of structural control. Further, each parameter has been assigned their ranks according to their value. The basin with lowest parameter value is ranked as first. It was considered as high priority for adopting conservation measure as well. The suitable locations for conservation measure structures in highly prioritized sub-watersheds were also identified for the appropriate land and water management plane. The relevance of work shows the appropriate measure structure locations for preventing the soil from getting eroded from the highly prioritized sub-watershed. INWASCON OPEN ACCESS
