This chapter introduces the themes and arguments of the book. In particular, it explains the benefits of adopting a holistic approach to the history of the river basin that acknowledges its cultural, physical, and biological unity. Treating the Tigris and Euphrates as a continuous whole brings to light the magnitude and significance of river flow that fostered contacts between upstream and downstream regions. Beyond facilitating communication, the twin rivers formed the backbone of the early modern Ottoman economy in the region by supporting complementary subsistence strategies, such as irrigation agriculture, animal husbandry, and wetland exploitation. In addition to the themes and arguments, this chapter offers a brief introduction to the history of the Ottoman Empire and the ecology of the Tigris-Euphrates basin.

Remedial Strategies

The Kaoping River Basin, located in southern Taiwan, flows through approximately 171 km and drains towards the South Taiwan Strait. It is the largest and the most intensively used river basin in Taiwan. Based on the results from the pollutant sources investigation and water quality analysis, the main water pollution sources of the Kaoping River were livestock wastewater from hog farms, municipal wastewater, industrial wastewater, leachate from riverbank landfills, and non-point source (NPS) pollutants from agricultural areas in the upper catchment. Concern about the deteriorating condition of the river led the Government of Taiwan to amend the relevant legislation and strengthen the enforcement of the discharge regulations to effectively manage the river and control the pollution. The following remedial strategies have been taken to improve the river water quality since 2001: (1) hog ban in the upper catchment of the Kaoping River Basin, thus, 510 thousand hogs have been removed/relocated; (2) removal of riverbank landfills; (3) enforcement of the industrial wastewater discharge standards; (4) sewer system construction in five cities along the river corridor; (5) application of best management practices for NPS pollutant control; (6) application of natural wastewater treatment systems (e.g. land treatment, constructed wetland, overland flow, riverbank sedimentation/aeration pond) for domestic wastewater treatment in rural areas; and (7) construction of the watershed geographical information system (GIS) and real time water quality monitoring system to effectively monitor and manage the watershed. Recent water quality investigation results indicate that the biochemical oxygen demand (BOD) and nutrient loadings to the Kaoping River have been significantly reduced and the water quality has been improved after the implementation of the remedial strategies described above. Results and experience obtained from this study will be helpful in designing the watershed management strategies for other similar river basins.

Water is linked to every facet of human development and prosperity. This paper seeks to capture the grassroots interventions undertaken by industry in improving the management of water resources. As water can directly impact the livelihood therefore the conservation, revival and development of water resources calls for a comprehensive and holistic approach. It puts into perspective the operational modality of industry in engaging with the community and improving the management of water resources. The objective is to provide a dynamic insight into the operational model of the industry in addressing the accumulated neglect in the water sector. An assessment of the operating model reiterates the positive social, economic, and environmental outcome in a sustainable manner. Therefore, it is proposed to explore operating beyond the level of “watershed” to larger level “river basin”. Going forward it is imperative to revive a culture of community base management of natural resources.

Hydroclimatic extremes such as droughts and floods triggered by human-induced climate change are causing severe damage in the Nile River Basin (NRB). These hydroclimatic extremes are not well studied in a holistic approach in NRB. In this study, the Gravity Recovery and Climate Experiment (GRACE) mission and its Follow on mission (GRACE-FO) derived indices and other standardized hydroclimatic indices are computed for developing monitoring and evaluation methods of flood and drought. We evaluated extreme hydroclimatic conditions by using GRACE/GRACE-FO derived indices such as water storage deficits Index (WSDI); and standardized hydroclimatic indices (i.e., Palmer Drought Severity Index (PDSI) and others). This study showed that during 1950–2019, eight major floods and ten droughts events were identified based on standardized-indices and GRACE/GRACE-FO-derived indices. Standardized-indices mostly underestimated the drought and flood severity level compared to GRACE/GRACE-FO derived indices. Among standardized indices PDSI show highest correlation (r2 = 0.72) with WSDI. GRACE-/GRACE-FO-derived indices can capture all major flood and drought events; hence, it may be an ideal substitute for data-scarce hydro-meteorological sites. Therefore, the proposed framework can serve as a useful tool for flood and drought monitoring and a better understanding of extreme hydroclimatic conditions in NRB and other similar climatic regions.

Wide Range

River water resources provide a wide range of necessary ecosystem services, including regulating, provisioning, supporting and cultural services. Ecosystem services are linked to an appropriate level of functionality of river water resource processes, which can be connected with river basin environmental objectives. Environmental objectives can be achieved only if appropriate flow and sediment regimes and related river morphology quality are guaranteed. The obligation to define environmental flow (E-flow) in the European Union Water Framework Directive European (WFD) is not explicit, and the implementation of the WFD is more focused on water quality. Considering the specific climatic, hydrographic and hydrological conditions and the definition of E-flow, each EU country has developed procedures for their investigation and determination. In the Republic of Croatia, no methodology has been elaborated, nor is there any legal regulation to define E-flow downstream of a dam or water intake site. This paper presents the significant pressures that have affected the transboundary rural Sutla River basin between Croatia and Slovenia. These pressures can cause changes in the hydrological regime and biological elements of water quality. The holistic approach defines the E-flow for a profile on the Sutla River by linking hydrological, morphological, and ecological characteristics based on the exploration of the Sutla River and its biological communities. The full implementation of a holistic approach and the transition to Level III of the E-flow definition requires the enhancement of exploratory hydrological and biological monitoring that enables the use of habitat modelling. Doi: 10.28991/cej-2020-03091611 Full Text: PDF

Anthropogenic Modifications

The protection and sustainable management of the aquatic ecosystems is the central aim of the European Water Framework Directive. Due to the aspiration for good ecological status of the water bodies free fish passage will play an important part in river basin management. The Ruhr River has seen severe anthropogenic modifications due to urbanisation and industrialisation in the 19th and 20th centuries leading in the existence of approx. 1,300 weirs within the Ruhr River Basin. The majority of the barriers are assessed as not passable or restricted passable. Against this background the Ruhrverband made a holistic approach towards restoring fish passage within the Ruhr catchment. Besides the scientific and technical aspects, such as the determination of potential (spawning) habitats and the development of measures in order to reach them, they also considered cost-benefit-ratio considerations for the Ruhr catchment as a whole as well as for site-specific designs of fish passage structures. Various benefits were evaluated taking into account different fields of economic interest. The model of financing all necessary measures should involve all responsible parties benefiting from the water utilizations. Such a mutual procedure delivers a fair cost distribution as well as an efficient implementation of measures.
