Due to inadequate rainfall, groundwater has acquired a vital role in the development of Pakistan's agricultural economy. However, a lack of awareness concerning the use of groundwater, either by itself or combined with canal water, has added large amounts of salt to the soil. As a result, large tracts of irrigated lands are already salinized, while many others are under threat. This report presents the results of a modeling study carried out to evaluate the long-term effects of a different quality of irrigation water on root zone salinity. The simulations were performed for the Rechna Doab (sub basin of the Indus Basin) in Pakistan, by using 15 years of actual rainfall and climatic data.

This study uses both farmer surveys and physical measurements to understand the impact RCTs have had on water use and water savings in the irrigated Rice-Wheat Zone of Pakistan's Punjab province. The findings show that field scale water savings achieved from RCTs is not necessarily equivalent to water savings at broader scales and may even result in an increase in overall water depletion.

Streamflow data is a prerequisite for planning and management of water resources. However, in many cases, observed streamflow data are not available or the records are too short or of insufficient quality. This undermines the informed planning and management of water resources at a specific site and as well as at the river basin scale. The study examines the possibility of simulating time series of streamflows for ungauged catchments based on hydrological similarity, using the mountainous, semiarid Karkheh river basin (55,000 km2, Iran) as an example. The main research question examined in this paper is whether or not the parameters of a hydrological model applied to gauged catchments can be successfully transferred for simulating streamflows in hydrologically similar ungauged catchments. In this study, the HBV model is applied to simulate daily streamflow with parameters transferred from gauged basin counterparts. Different similarity measures were reviewed and finally the approach based on the shape of the flow duration curve (FDC) was used. FDCs are frequently used for comparing the response of gauged catchments and for estimating hydrological indices for ungauged catchments, but their potential use for the regionalization of conceptual rainfall runoff models to ungauged catchments needs to be explored and is a subject of this paper. FDCs for ungauged basins are defined using developed regional regression relationships between the parameters of a logarithmic FDC model and physiographic catchment characteristics of eleven gauged catchments. The results suggest that the proposed method could be successfully applied for the estimation of ungauged streamflows in the mountainous parts of the Karkheh river basin. Then the estimated ungauged streamflows were used as an input to conduct water balance analysis of main river reaches of Karkheh river system. The utility of this information is demonstrated in closing the water balance, scenario analysis for surface water allocation and identification of river reaches where further hydrological investigations are crucial.

Water-limited environments occupy about half of the global land area and are highly sensitive to change due to scarcity and variable distribution of water and nutrients. The Karkheh basin in Iran is in a water limited region which exhibits increasing competition for scarce water resources between irrigation, domestic, hydropower and environmental needs. Increasing demands for water are making sustainable water management more and more difficult particularly because of lack of understanding of basin hydrology and impacts of water resource development on different users across the basin. An in-depth study was conducted to examine the inter-annual and long-term variability of surface water resource using daily stream flow data from 1961 to 2001 at seven key locations across the Karkheh basin. The water accounting at basin scale was carried out using the available information for the water year 1993-94, which is considered in Iran as the reference year for future development and allocation of water resources in the Karkheh basin. The analysis reveals that water allocation planning on the basis of mean annual surface water availability can only provide a supply security of about 45 %, ranging from 40 to 52 percent. Although, the water allocations to different sectors are lower than the available resources and the competition among different sectors of water use is minimal during the study period, it would be extremely difficult to meet the demands in future i.e. by 2025, as planned allocation will reach close to the annual renewable water resources available in an average climatic year. The competition among irrigation and other sectors will keep increasing in future, particularly during dry years. The analysis conducted in this study is helpful in gaining further insights into the hydrological variability of surface water resources and incorporating it into water development and allocation strategies that will contribute in ensuring the sustained productivity from irrigated agriculture and other uses of water in the coming decades.
