Answer:
1. The Coastal Plains of Gujarat: This forms the north portion of the west coast. It is quite wide. The lowland in the Kachchh region from marshes and are called Rann. In the monsoon this entire Rann region lies under water. In the past, the Gulf of Khambhat extended into the Rann of Kachchh and the Kathiawar Peninsula was an island.
2. The Coastal Plain of the Konkan: From Daman in the north to Goa in the south lays the Konkan Coastal Plain. This plain extends for 500 km but is very narrow and broken. No other coastal plain of India is so narrow. Most of the plain is formed of rock. Through the northern part of this coast flows the Baitarani River.
3. The Coastal Plains of Karnataka: South of the Konkan coast starts the coastal plains of Karnataka between Goa in the north and Mangalore in the south, for 225 km. Though this coastal plain is narrow it is wider near Mangalore 70 km. At many places along the coast the plain is sandy and at some places the Western Ghat reaches the sea. To the east of this plain lies the highest waterfall of India, called Jog or Gersoppa which falls across the Sharavati River. The height of the fall is 275 meters.
4. The Coastal Plains of Malabar: The extreme southern part of the west coal plain lies in the state of Kerala and is called the Malabar Coast. Compared to the Konkan and Karnataka Coastal plains this is the widest at 25 km on average.
5. Lagoons: There are many sand dunes, lakes or lagoons along the Malabar Coast. The local people call these lagoons Kayal e.g. the 80 km long Vembanad Kayall near Kochi and the Ashtamudi Kayal near Kollan (Quilon) are famous.
Importance of coastal plains of IndiaThe fertile plains along the coast produce large amounts of rice, sugarcane, coconut, various spices etc.Through the ports of Mumbai, Chennai, Mormugao, Kochi (Cochin) etc most of the international trade of India is conducted.Large amount of salt is produced from the northern part of the west coastal plain from sea water.Mineral Oil and Natural Gas is either being extracted or possibility of the resources being present is very probable in the river valleys of Krishna, Godavari and Kauvery.Due to the suitable environment in the coastal regions population density is very high.Related Posts:

1. INTRODUCTION
Power System Stabilizers (PSSs) are widely used to damp the oscillation of the electrical machines in the power Esystem. Author Larsen designed the PSS based on the linear model of the plant using a particular operating point [1]. However, in almost all the power systems are nonlinear and the operating point are also not constant frequently changes with respect to the operating condition. Therefore, the performance of a conventional power system stabilizer (CPSS) may deteriorate under variations that result from nonlinear and time-variant characteristics of the controlled plant. The PSS with the high sensitive to wide range of operating conditions, artificial intelligence approaches can be proposed based on fuzzy logic [2]–[4]. Similarly artificial neural networks [5] and Neuro-fuzzy based PSS have been presented in [6]–[7]. The application of robust control methods for designing PSS has been presented in [8]–[10] and adaptive control algorithms based PSS is presented in [11]–[13].
