AbstractIn recent years, it has become popular for some of countries and regions to adapt the system of governance to varied and complex issues concerned with regional development and the environment. Watershed management is possibly the best example of this. It involves flood control, water use management and river environment simultaneously. Therefore, comprehensive watershed-based management should be aimed at balancing those aims. The objectives of this study are to introduce the notion of environmental governance into the planning process, to establish a method for assessing the alternatives and to develop a procedure for determining the most appropriate plan for environmental governance. The planning process here is based on strategic environment assessment (SEA). To verify the hypothetical approach, the middle river basin in the Tokachi River, Japan was selected as a case study. In practice, after workshop discussions, it was found to have the appropriate degree of consensus based on the balance of flood control and environmental protection in the watershed.

And Control

A system of reservoirs is usually defined as a system of water management elements, that are mutually linked by inner and outer connections in a purpose-built complex. Combined elements consist of reservoirs, river sections, dams, weirs, hydropower plants, water treatment plants and other hydraulic structures. These elements also include the rainfall system, the run-off system, the ground water system, etc. A system of reservoirs serves many purposes, which result from the basic functions of water reservoirs: storage, flood control and environmental functions. Most reservoirs serve several purposes at the same time. They are so called multi-purposes reservoirs. Optimum design and control of a system of reservoirs depends strongly on identifying the particular purposes. In order to assess these purposes and to evaluate the appropriate set of criteria, risk analysis can be used. Design and control of water reservoir functions is consequently solved with the use of multi-objective optimisation. This paper deals with the use of the risk analysis to determine criteria for controlling the system. This approach is tested on a case study of the Pastviny dam in the Czech Republic.

The last few decades we have witnessed an enormous rise in awareness of the importance of wetlands. Mathura beel1 has been assumed to take the attention in recent years because of its ecological significance in terms of flood control, water purification, aquatic productivity, and microclimatic regulation etc. The aim of this paper is to present a complete scenario of Mathura beel through different analyses. To materialize the main objective, the water quality monitoring, socioeconomic analyses, and a perception study on wetland use and wetland threat are considered separately. In this study, the objective was extended to observe the complete socio-economic status, and a detailed perceptional study on wetland use, and wetland threat. At the end of the study, detailed management options have been given to protect and to conserve the economy and the ecosystem of Mathura beel.

Perkembangan pariwisata di kota Semarang ditandai dengan tersedianya fasilitas shuttle bus gratis. Rute shuttle bus tersebut melewati rute Kuliner Pekunden, Pusat oleh-oleh Pandanaran, Gedung Lawang Sewu dan Daerah Kota Lama Semarang.Sejak tahun 2012, wisata di tepi Sungai Kanal Banjir Barat mulai dikembangkan pemerintah Kota Semarang. Namun, sampai saat ini Kanal Banjir Barat hanya difungsikan sebagai sungai pengendali banjir, sehingga fungsi pariwisatanya belum optimal seperti objek wisata lain di Kota Semarang. Tujuan dari penelitian ini adalah untuk mengembangkan transportasi wisata air, khususnya di Kanal Banjir Barat. Penelitian ini menggunakan metode deskriptif dengan kuesioner dan observasi lapangan. Metode kuantitatif penentuan alur pelayaran menggunakan analisis hidrologi dan simulasi hidrolika sungai dengan program HEC-RAS. Penelitian ini merekomendasikan bahwa lokasi pengembangan transportasi untuk wisata air di Kanal Banjir Barat akan efektif jika berada diantara Bendung Simongan hingga muara Kanal Banjir Barat. Tipe angkutan wisata yang ideal adalah menggunakan 2 kapal speedboat terbuka dengan dimensi panjang 8 m, lebar 2,2 m, dan draft 0,4 m. Biaya Operasional Kapal per tahun untuk 8 trip per hari dan biaya pengelolaannya adalah sebesar Rp 901,2 juta dengan estimasi tarif per orang sebesar untuk Rp 17.070,- per trip. [Title: River Transportation Development of Semarang City for Water Tourism: A Case Study West Flood Canal] Tourism development of Semarang city is identified by the facilities of free shuttle bus. The shuttle bus service passes through Pekunden culinary route, a central souvenir of Pandanaran, Lawang Sewu and Old City of Semarang. Since 2012, local government has developed riverside tourism object of the West Flood Canal Semarang. However, until then the West Flood Canal only was functioned as flood control. Thus, the tourism function is not optimum as other tourism attractions in Semarang city. This research aims to develop the water tourism transportation, especially in the West Flood Canal. This research uses a descriptive method by questionnaires and field observations. Quantitative methods of determining ship channel using hydrological analysis and simulation of river hydraulics with HEC-RAS program. This study recommends that the location of the development of transportation of water tourism in the West Flood Canal would be effective if it is located in between the estuary of Simongan weir to the West Flood Canal. The ideal type of transport mode uses two open speedboats with dimensions of 8 m length, 2.2 m width, and a draft of 0.4 m. Ship Operating Costs per year for eight trips per day and its management fee is Rp 901.2 million with the estimated fare per person about USD 17.070, - per trip.
