Mathematic model about the Miter Gates used in the Panama Canal
I study in the Universidad Tecnologica de Panama, and I'm doing my thesis. In this thesis I need to make a Mathematic Model about the Miter Gates used in the Panama Canal. I need some help to make a model about the water currents and how this currents affect the gates and how the gates movement generate some water currents. Can you help me with this model? I'm doing an investigation in the Engineer Branch. The Miter Gates of the Panama Canal are moved by an electromechanical mechanism (electric motor, reduction box, gears and a strut arm). At this time the Panama Canal Authority is changing this system by an hydraulic one this new system was designed and manufactured by Rexroth Corporation. At this time a complete lock use this hydraulic system and some problems are emerging, problems that We don't have with the old system. The main reason to do this model is predict the behaviour of the Miter Gates and compare this with the hydraulic mechanism performance. I'll be very thankful for all the help that you provide to us.

Morphodynamic modeling of biogenic sand beaches
I am looking for references (or gray papers) on the morphodynamic modeling of biogenic (e.g. calcareous) sand beaches using MIKE-21 model. Any suggestions or personal experiences would be gratefully received. Dr. Isaac Azuz-Adeath, Strategic Development Center, CETYS-University (Mexico). Iazuz@mail.ens.cetys.m

Predicting the degree of development of point bars
We are working on methods to obtain areas of fish habitat on point bars in a meandering alluvial river on the Canadian prairies. I am wondering if there are algorhythms out there for predicting the degree of development of point bars in relation to radius of curvature of meander bends or if someone has practical experience in obtaining point bar areas in relation to hydraulic parameters in meandering rivers. PS I am a fishery biologist, not an engineer or physicist but I am aware of some of the literature along these lines. Just inquiring if there is a model out there we can test with field data.

Beach response to submerged breakwaters
I am currently looking at beach response to submerged breakwaters. However, my lit. searches upto now on the said topic have not been too fruitful. Could any of you direct me to articles regarding the measurement or modelling (physical or numerical) of the above phenomenon? Any help would be greatly appreciated.

Studies on the roughness of floodpain and marsh vegetation
Within the framework of the development of a handbook for vegetation roughness in floodplains by Public Works Department, The Netherlands, Delft Hydraulics is preparing a data base with results of flume and prototype measurements of the roughness of (flexible) submerged vegetation. Therefore we are trying to identify and locate well documented (older and more recent) studies on the roughness of this type of floodpain and marsh vegetation, in order to include the measuring data into our database. We will also include vegetation in weeded canals as far as it can help us in improving our understanding of the roughness of submerged plants. Our main interest though is flexible, low vegetation like grasses, reeds, and other marsh vegetation, which is substantially submerged during flood conditions. We do not intent to include data on rigid vegetation like willows and trees. In principle our interest is natural plants, but we will include as a side activity also data on artificial "plants" like rods and strips. We have already started the preparation of a data set, and for the time being it is (of course) limited to literature we could identify until now. We can send you a copy of the list of reports and articles from which data are already being included. If you have useful information and/or are interested in the list, you can contact us via the below e-mail address. If you - after having scutinized the list - are aware of additional detailed and well-documented studies on the roughness of (flexible) submerged vegetation, we invite you to contact us. Moreover we would appreciate to be informed on any persons or institutes involved in research on this subject. Chris Stolker & Gerrit J. Klaassen Delft Hydraulics, P.O. Box 177 2600 MH Delft The Netherlands e-mail: Chris.Stolker@wldelft.nl

Impact of offshore sand mining
I am Wijayanto, I have been working for Coral Reef Rehabilitation and Management Program (COREMAP) at Regional Planning and Development Board of Riau Province, Indonesia.
Does anyone can explain or have any references regarding the impact of offshore sand mining. I am very grateful if you can help me to save our island and coral reef.

The effect of vegetation on sediment deposition
We are currently working on a project that requires estimation of the effect of vegetation on sediment deposition. The vegetation ranges from grass to brush and trees, and is located in a tropical environment. In addition to increasing the hydraulic roughness and slowing the flow down, it appears as if additional sediment is trapped by the physical presence of the vegetation.
We are looking for research results pertaining to this topic, and, preferably, recommendations on how to simulate the phenomena by numerical modeling. Please forward references or recommendations if you have any.

The 3-year project will start around August 2000. Groups from Israel, Spain, Netherlands, France and Great Britain will be our partners in the project. Field sites will be available for practical work. But also lab experients will be at our disposal. The modelling effort should look into the impact of heterogeneous structures on salt water intrusion and upcoming processes. Also, the fingering of heavy brine and its modelling is one of the objectives. The applicant could be an environmental engineer/scientist, hydrogeologist, hydrodynamicist or physicist. Extensive experience with modelling is required. Please apply to: Prof. W. Kinzelbach, IHW, ETH Hoenggerberg, CH-8093 Zürich (e-mail address: kinzelbach@ihw.baug.ethz.ch) with the usual materials on your person.
