| Abstract | A potential ungauged water-harvesting site was chosen in the central Riyadh Region of Saudi Arabia. A hydrological study was carried out on the catchment area from which runoff water will be diverted to the chosen site. Rainfall depth records from three neighboring rain gauges were used. Runoff volumes and peak discharges for the 2-, 5-, and 10-year storms were estimated using three methods, namely, (a) Soil Conservation Service (SCS) Dimensionless Unit Hydrograph (DUH) method assuming Gumbel distribution for rainfall depth analysis, (b) HEC-HMS modeling, and (c) the modified Talbot formula. The results show that the modified Talbot formula yields an order of magnitude higher peak discharge values for all return periods. The SCS-DUH method and HEC-HMS modeling provide comparable estimates for the peak discharges and runoff volumes. The peak discharges obtained through the Hydrologic Engineering Center-Hydrologic Modeling System (HEC-HMS) model for the 2-, 5-, and 10-year storms are 0.17, 0.83, and 1.34 times than those obtained by the SCS-DUH, respectively. The HEC-HMS runoff volume estimates are 0.18, 0.85, and 1.36 times than those estimated by the SCS-DUH for the 2-, 5-, and 10-year storms, respectively. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
