Abstract

This paper presents the results of triaxial tests on soft Hong Kong marine deposits (HKMD) without or with cement treatment. Special attentions are paid to the features of stress-strain relationships and the effective stress paths. Useful correlation (a) between index properties and strength parameters and (b) cement ratio and strength parameters and Young's modulus are presented. The data presented are of practical significance for design and construction of civil works on HKMD in Hong Kong.

Abstract

Many coastal lowlands are recently deposited. That is the soil layer consists of a thick layer of normally consolidated clay, silty clay, clayey silt or a combination thereof. In certain areas the deposit is so soft at the grade level that it cannor support the slightest of loads. In other areas, perhaps a few kilometers away from the shore-line, the surficial soils have become over-consolidated by desiccation and can support some load. These localities are, more often than not, of very gentle slope and carry scant vegetation. The layer supportng the crust (the desiccated soil) is still normally consolidated, highly compressible and its water content often exceeds the LL. Construction on such a formation obviously presents a serious problem and certain guidelines may be of value. It is the aim of the present paper to provide some such information. The discussions are limited to the performance of strip footing for low cost single story housing units.

Abstract

In lowlands comprised of soft ground, land subsidence due to excessive groundwater pumping causes many problems, including damage to roads and structures, and an increased risk of flood due to the reduced drainage capacity of the system. Subsidence in Saga Plain, Japan, has been caused by fluctuating groundwater levels due to summer pumping for agriculture and winter recharge. The nature of land subsidence due to these groundwater level fluctuations is the focus of this paper. The characteristics of land subsidence and groundwater level were identified in both the Holocene clays and Pleistocene aquifer that form the hydrological system of the Saga Plain.

Abstract

Egyptian wetlands are classified into two broad categories: coastal adn inland wetlands. The major problem of coastal wetlands, which are located in the northerm part of the Nile Delta, is the environmental impacts caused by the intrusion of saline water into fresh water aquifer. Inland wetlands, which are often located in the depressions of western desert or other areas along the Nile Valley, can be further classified as either natural wetland such as Wadi Elnatrun depression, or manmade wetland such as Siwa oasis. The associated problems in manmade wetlands comprise the groundwater abstraction which often exceeds the actual need, the negative impact of upland drainage on neighboring lowland, and the rise of groundwater table in agricultural lands due to illegal alteration of irrigation systems by farmers. Another type of manmade wetlands is the riverine land, which was existed in south of Egypt after the construction of Aswan High Dam and caused dramatic migration for some living societies and relocation of some historical monument. This review addresses the current problems faced by those coastal and inland wetlands, and illutrates the mitigation systems proposed in Egypt for tackling such problems.

Abstract

Tidal flats of the estuarine ecosystem, reef flats of the coral ecosystems and mangrove ecosystems have up until now ensured the food availability of biologically diverse marine resources on a year-round basis. Traditionally, fishing-gleaning activities have been carried out on a daily basis by women, children and the agedm using non-specialized tecniques or technologies on reef flats in the Ariake Sea, Japan and along the west coast of South Korea. These flats and mangrove ecosystems are covered by the sea twice a day when the tide is at flood, and they are uncovered at ebb. Therefore, it has given people the opportunity to enjoy a supply of oysters and other marine resoources two times a day since ancient times. Oyster-gathering activities through traditional fishing-gleaning strategies on tidal flats in Japan and Korea are, in this study, focused on and discussed in terms of ecological anthropology.

Abstract

This paper deals with the Consumptive Use (U) and the Field Irrigation Requirement (FIR) for rice crop during the dry period of the Jessore district in the Ganges lowland of southwest Bnagladesh by using the Blaney-Criddle Method. The estimated U ranges from 3.11 mm/d in December to 7.65 mm/d in April. The minimum and maximum estimated FIR for rice crop in the months of December and April is about 3.54 mm/d and 6.61 mm/d, respectively. The total seasonal FIR is about 807 mm for rice crop during the present dry period. The above results may prove useful for the future planning of a rice crop-design calendar of the Jessore district during the dry period
