Presentation on The Modeling Experience of MOWE • Introduction • General concept and use of models • Experiences of Modeling in the MOWE • Capacity and Challenges • Way Forward
12 basins with 1.13M Sq Km A surface water resource of 122BM3 Ground water resource more than 35BM3 and also under study Challenges in terms of development, management optimization that needs reliable tools Introduction
GENERAL CONCEPT, TYPE AND USE OF MODELS General Concept • Models in water resource management are tools that are used to inform decisions about water resources in quantity and quality, Environmental, and water management in Complex regional systems. Type of models • Simulation and optimization models • Hydrological and meteorological models • Disaster management models • Water quality models • Design models
USE OF MODELS • Estimate runoff from watersheds • predict interactions between ground-water and surface water bodies • used to study reservoir operation; to forecast floods and plan flood-control programs; to predict, embankment erosion, and dam breaks; and to plan for ecosystem restoration. • for the real-time operation and management of water systems and for assessing water supply availability and reliability • used for determining facility-size requirements for water storage and distribution systems • predict changes in a river bed form and location, including bank erosion, scouring, changes in the hydraulic regime, and so on. • used for morphological studies in small- and large-scale rivers of all kinds and in all settings, as well in reservoirs. • Evaluate alternative water allocation scenario and assist in assessing the impact of intervention
EXPERIENCE OF MODELING WITHIN THE MINISTRY • The Ministry of Water and Energy has been developing models for years as part of the Integrated Basin Development Master Plan Studies as well as other specific studies • most of the models are developed by consultants and, some experiences using in house staffs • Relevant directorates in water resources modeling activities are Hydrology and Water Quality, Basin Administration Directorate, Water Use Permit and Administration Directorate, Environmental Impact Assessment and Social Development Office, Energy ….. And Research Directorates
MODELING CAPACITY AND CHALLENGES Modeling Capacity • Modeling capacity within the Ministry is very low • Some practical experiences in some directorates • Need to establish modeling unit • Some Modeling soft-wares and equipments available Challenges • No adequate experienced staff • There is high turnover of staffs that are trained in modeling • Lack of Modeling tools and Equipments • There is No take over of the activities undertaken by different studies
Future Direction • concentrate on checking, updating and make use of existing models for operational purposes • Integration among different directorates • Capacity development, human and institutional • Co-operate with different stakeholders, universities and institutes that are working in modeling
Practical Experiences Main Activities • Reservoir Management • Flood forecasting, monitoring and control Tools • Forecasting using simple EXEL models • Forecasting using models like HEC-HMS, MIKE II • Monitoring near real time data
Fogera Rivers (Gumara and Ribb): Peak flood is expected in the evening of 15th and in the morning of 16th September, 2012 (around midnight) Dembiya Rivers (Dirma and Megech): Peak flood is expected in the early morning of 16 September 2012 (around 3:00 AM) • Runoff forecast as upon 14th of September 2012
Runoff forecast as upon 14th of September 2012, (Fogera floodplain)
