Flood Intensification due to Changes in Land Use

The non-stationarity in runoff regime may be attributed to various causes such as climate change, land use change, and man-made runoff control structures. Degradation of land use can induce significant impact on infiltration and surface roughness leading to higher flood discharges. This study aims at quantifying possible effects of land use changes and identifying flood source areas for future flood control planning in the Golestan watershed located northeast of Iran. A preliminary trend analysis on the annual maximum flood record of three stations inside the watershed showed that two stations were subject to anthropogenic change. This is while no trend could be detected in the annual maximum rainfall records in the region. Using a calibrated event-based rainfall-runoff model, flood hydrographs corresponding to land use conditions in 1967 and 1996 were simulated and relative changes in the peak flow of the two subsequent conditions were determined for different return periods. The results showed that the impact of land use changes on the flood peak discharge is considerably greater in some subwatersheds. Two limiting land use scenarios were also considered to investigate the envelope of future flood peaks in the watershed. By successively eliminating subwatersheds from the simulation process in a method titled "unit flood response”, the contribution of each subwatershed to the outlet flood peak was quantified. Contribution, per unit area, to the outlet flood peak was the basis to rank the subwatersheds in terms of their flood potential.     

Intensification of freezing earth hydraulic structures by natural cold

Conclusion At the given stage the described suggestion has been substantiated by calculation, and therefore as the next stage it is necessary to conduct a full-scale experiment, which will make it possible to work out practical recommendations on using this suggestion when constructing earth dams and various embankments, when conducting maintenance and reconstruction works on industrial waste dumps, etc.The use of the proposed method will markedly reduce the time and cost of conducting construction and maintenance works.Translated from Gidrotekhnicheskoe Stroitel'stvo, No. 11, pp. 18–20, November, 1991.     

Water Planning in Jordan

Abstract

This paper present a shift in water planning in Jordan from supply-side water management to more integrated and demand-driven water management. Assessment of existing water supply and demand is presented and strategies are outlined. Potential available water resources and uses are presented. Strategies to meet unsatisfied water demand are presented. These include use of nonconventional water resources, privatization, efficiency enhancement in distribution systems, and demand management. Scenarios for sustainable water management are developed. Each scenario was based on combinations of the role of government in the water sector and the national financial situation. Comparisons among these scenarios were performed for the case of Jordan and a set of recommendations are stated.     

Intensification of sonochemical degradation of phenol using additives at pilot scale operation

The present work reports the use of sonochemical reactors for the degradation of phenol in the presence of additives with an objective of enhancing the rates of degradation at a pilot scale operation. Process intensification studies have been carried out using additives such as hydrogen peroxide (H2O2) (0.5-2.0 g/L), sodium chloride (0.5-1.5 g/L) and solid particles viz. cupric oxide (CuO) and titanium dioxide (TiO2) (0.5-2.5 g/L). Optimum concentration for H2O2 and sodium chloride has been observed beyond which no beneficial effects are obtained even with additional loadings. Maximum extent of degradation has been observed by using ultrasound/H2O2/CuO approach at a solid loading of 1.5 g/L followed by ultrasound/H2O2/TiO2 approach at a loading of 2.0 g/L. The obtained results at pilot scale operation in the current work are very important especially due to the fact that the majority of earlier studies are at laboratory scale which cannot provide the design related information for large scale operation as required scale up ratios are quite high adding a degree of uncertainty in the design. The novelty of the present work lies in the fact that it highlights successful application of sonochemical reactors for wastewater treatment at pilot scale operation.     

Intensification of 330/400 kV power transmission in the back-to-back project connecting Russia and Finland

It is shown that the fourth converter unit with a capacity of 350 MW commissioned in 2000 at the Vyborg back-to-back direct-current converter station connecting the power systems of Russia and Finland increased the total installed power of the converter units to 1400 MW. The circuitry of the converter station and its connections permits two independent transmissions through the Vyborg substation with mutual redundancy and with allowance for the requirements of the receiving power system with respect to the maximum power of each transmission. Normal and emergency operating conditions are described. Difficulties encountered in the course of the work and measures taken for their elimination are discussed.Translated from Élektricheskie Stantsii, No. 10, October 2004, pp. 50–55.

Groundwater Use for Irrigation and its Productivity: Status and Opportunities for Crop Intensification for Food Security in Bangladesh

Bangladesh has a large and growing population that will demand more food and place greater pressure on resources. Dry season irrigated Boro rice production is important for national food security. Dry season irrigation mainly uses groundwater, but the extent of its use is not well known. We assessed groundwater use and water productivity of Boro in the northwest region of Bangladesh using remote sensing based energy balance modelling, crop classification and secondary statistics. The energy balance modelling shows a large spatial variation in the actual evapotranspiration (ET_a) from about 325 to 470 mm, with an overall spatial average of 365 mm during dry season. The estimated values of ET_a correspond well with independent values from field and regional scale soil and water balance modelling results. From spatial estimates of ET_a and effective rainfall, we computed regional net groundwater use for Boro production in 2009 as 2.4 km³. Groundwater is being used unsustainably in some areas, and a spatial time series (1990 to 2010) of pre- and post-monsoon groundwater depth changes in the northwest region of Bangladesh suggests that, with the current level of groundwater use, falling groundwater levels may pose a long term threat to the sustainability of irrigated agriculture in much of the region. Boro water productivity varies from 0.95 to 1.35 kg/m³, allowing the identification of high performing “bright” and low performing “hot” spots and the development of strategies to reduce crop yield/productivity gaps and ensure future food security.
