PREVIOUS STUDIES IN THE STUDY AREA
Existing and applied Water Resources Systems: - Seasonal Rainfall Forecasting (Jessen, 2001);- Flood Watch Model (DHI, 2009);- Comparison of two model approaches in the
Zambezi river basin with regard to model reliability and identifiably (Winsemius et al., 2006);
- Impact of climatic Changes on hydrology (Asante and Vilanculos, 2009).

BACKGROUND: Problem and Motivation
Problem statement:• 30 million in 2030 70 million• Pop. growth will increase water
demand for agric. And energy• 80% population lives on rainfed
agriculture• Irrigation potential more than 3
million ha only 5% are developed• Poor ground hydro-climatic

Water Resources Potential - Climatic and Hydrology
Hydrology: River and Discharge• Lukulo river - 4.1 km3/year• Zambezi river - 33.5 km3/year• Kafue river - 10 km3/year• Luangwa river - 22 km3/year• Shiri River - 16 km3/year• Kabora Bassa lake - 77.5 km3/year • Malawi Lake - 29 km3/year• Shiri Out flow to Moz- 12.5 km3/year
Rainfall: Range from 570mm/year (Simi Arid Area central to 2190mm/year in East and North

AIMS OF THE STUDY
• Identify the interlinking between up and downstream WRMS.
• Identify the relationship to be made between power generation and flood impacts downstream.
• To develop a or no coordinated methodology for daily/monthly operating strategies in the Zambezi River Basin.

METHODOLOGY
Identification of current WRMS and Selection of an existing WRMS FrameworkUse of a selected WRMS for:
- Delineation of preliminary boundaries- Calculation of daily soil water balance and flow- Selection of the monitoring and calibration sites- Run preliminary model in various scenarios (with and
without Dam discharges connected) and predicting the impacts downstreamFlood Risk Analysis at Downstream Statistics Analysis

CASE STUDIES
1. Existing Water Resources Management Systems in the
Zambezi River Basin
- Quest.: What are the WRMS existing in the Study area?
2. Hydrological Scale in Hydrological Models
- Quest.: How do different scale hydrological models link with each other?
3. Balancing water for power generation and for other users downstream
- Quest.: What is the role of implementing of a muiltreservoir operation system on the integrated river basin management ?

EXPECTED RESULTS
• Doctoral thesis in hydrology.• Knowledge on downstream implication from
upstream operational reservoir in the Zambezi basin.
• Knowledge on definition of optimal hydropower reservoir operation.
• Guidelines on how well the multi-reservoir systems in series and parallels can be operated in beneficial main through integrated water resources system framework
